GtkTreeStore as GtkBuildable

The GtkTreeStore implementation of the GtkBuildable interface allows to specify the model columns with a <columns> element that may contain multiple <column> elements, each specifying one model column. The “type” attribute specifies the data type for the column.

An example of a UI Definition fragment for a tree store:

<object class="GtkTreeStore">
  <columns>
    <column type="gchararray"/>
    <column type="gchararray"/>
    <column type="gint"/>
  </columns>
</object>

gtk_tree_store_new ()

GtkTreeStore *
gtk_tree_store_new (gint n_columns,
                    ...);

Creates a new tree store as with n_columns columns each of the types passed in. Note that only types derived from standard GObject fundamental types are supported.

As an example, gtk_tree_store_new (3, G_TYPE_INT, G_TYPE_STRING, GDK_TYPE_PIXBUF); will create a new GtkTreeStore with three columns, of type gint, gchararray, and GdkPixbuf respectively.

gtk_tree_store_newv ()

GtkTreeStore *
gtk_tree_store_newv (gint n_columns,
                     GType *types);

Non vararg creation function. Used primarily by language bindings.

gtk_tree_store_set_column_types ()

void
gtk_tree_store_set_column_types (GtkTreeStore *tree_store,
                                 gint n_columns,
                                 GType *types);

This function is meant primarily for GObjects that inherit from GtkTreeStore, and should only be used when constructing a new GtkTreeStore. It will not function after a row has been added, or a method on the GtkTreeModel interface is called.

gtk_tree_store_set_value ()

void
gtk_tree_store_set_value (GtkTreeStore *tree_store,
                          GtkTreeIter *iter,
                          gint column,
                          GValue *value);

Sets the data in the cell specified by iter and column . The type of value must be convertible to the type of the column.

gtk_tree_store_set ()

void
gtk_tree_store_set (GtkTreeStore *tree_store,
                    GtkTreeIter *iter,
                    ...);

Sets the value of one or more cells in the row referenced by iter . The variable argument list should contain integer column numbers, each column number followed by the value to be set. The list is terminated by a -1. For example, to set column 0 with type G_TYPE_STRING to “Foo”, you would write gtk_tree_store_set (store, iter, 0, "Foo", -1).

The value will be referenced by the store if it is a G_TYPE_OBJECT, and it will be copied if it is a G_TYPE_STRING or G_TYPE_BOXED.

gtk_tree_store_set_valist ()

void
gtk_tree_store_set_valist (GtkTreeStore *tree_store,
                           GtkTreeIter *iter,
                           va_list var_args);

See gtk_tree_store_set(); this version takes a va_list for use by language bindings.

gtk_tree_store_set_valuesv ()

void
gtk_tree_store_set_valuesv (GtkTreeStore *tree_store,
                            GtkTreeIter *iter,
                            gint *columns,
                            GValue *values,
                            gint n_values);

A variant of gtk_tree_store_set_valist() which takes the columns and values as two arrays, instead of varargs. This function is mainly intended for language bindings or in case the number of columns to change is not known until run-time.

gtk_tree_store_remove ()

gboolean
gtk_tree_store_remove (GtkTreeStore *tree_store,
                       GtkTreeIter *iter);

Removes iter from tree_store . After being removed, iter is set to the next valid row at that level, or invalidated if it previously pointed to the last one.

gtk_tree_store_insert ()

void
gtk_tree_store_insert (GtkTreeStore *tree_store,
                       GtkTreeIter *iter,
                       GtkTreeIter *parent,
                       gint position);

Creates a new row at position . If parent is non-NULL, then the row will be made a child of parent . Otherwise, the row will be created at the toplevel. If position is -1 or is larger than the number of rows at that level, then the new row will be inserted to the end of the list. iter will be changed to point to this new row. The row will be empty after this function is called. To fill in values, you need to call gtk_tree_store_set() or gtk_tree_store_set_value().

gtk_tree_store_insert_before ()

void
gtk_tree_store_insert_before (GtkTreeStore *tree_store,
                              GtkTreeIter *iter,
                              GtkTreeIter *parent,
                              GtkTreeIter *sibling);

Inserts a new row before sibling . If sibling is NULL, then the row will be appended to parent ’s children. If parent and sibling are NULL, then the row will be appended to the toplevel. If both sibling and parent are set, then parent must be the parent of sibling . When sibling is set, parent is optional.

iter will be changed to point to this new row. The row will be empty after this function is called. To fill in values, you need to call gtk_tree_store_set() or gtk_tree_store_set_value().

gtk_tree_store_insert_after ()

void
gtk_tree_store_insert_after (GtkTreeStore *tree_store,
                             GtkTreeIter *iter,
                             GtkTreeIter *parent,
                             GtkTreeIter *sibling);

Inserts a new row after sibling . If sibling is NULL, then the row will be prepended to parent ’s children. If parent and sibling are NULL, then the row will be prepended to the toplevel. If both sibling and parent are set, then parent must be the parent of sibling . When sibling is set, parent is optional.

iter will be changed to point to this new row. The row will be empty after this function is called. To fill in values, you need to call gtk_tree_store_set() or gtk_tree_store_set_value().

gtk_tree_store_insert_with_values ()

void
gtk_tree_store_insert_with_values (GtkTreeStore *tree_store,
                                   GtkTreeIter *iter,
                                   GtkTreeIter *parent,
                                   gint position,
                                   ...);

Creates a new row at position . iter will be changed to point to this new row. If position is -1, or larger than the number of rows on the list, then the new row will be appended to the list. The row will be filled with the values given to this function.

Calling gtk_tree_store_insert_with_values (tree_store, iter, position, ...) has the same effect as calling

1
2

gtk_tree_store_insert (tree_store, iter, position);
gtk_tree_store_set (tree_store, iter, ...);

with the different that the former will only emit a row_inserted signal, while the latter will emit row_inserted, row_changed and if the tree store is sorted, rows_reordered. Since emitting the rows_reordered signal repeatedly can affect the performance of the program, gtk_tree_store_insert_with_values() should generally be preferred when inserting rows in a sorted tree store.
